LINK.

Application filed July 19, 1923. Serial No. 652,612.

To all who-m it may concern:

Be it known that I, HORACE O. CLARK, a citizen of the United States,residing at VVaukegan, in the county of Lake and State of Illinois, haveinvented a new and useful Link, of which the following is aspecification.

This invention aims to provide a link, which, being used in duplicate,may be employed for uniting the ends of a broken cross chain on ananti-skidding device for vehicle tires, it being possible to use thelink in single form on the side chain of an anti-skidding device, andthe link being reinforced at one point, and weakened at other points, sothat the link may be closed partially, without difficulty, when the linkis used in single form.

It is within the province of the disclosure to improve generally and toenhance the utility of devices of that sort to which the inventionappertains.

With the above and other objects in view, the invention consists in thenovel construction and arrangement of parts hereinafter described, anddepicted in the drawings, it being understood that, within the scope ofwhat is claimed, a mechanic may make changes in the structure describedand delineated, without departing from the spirit of the invention.

In the drawings :Figure 1 shows in side elevation, a link constructed inaccordance with the invention; Figure 2 is a section on the line 22 ofFigure 1; Figure 3 is an elevation showing two links used as aconnector; Figure 4 is a view similar to Figure 3 but showing the linksas they will appear when they are pressed against the ground, in use;Figure 5 is a section on the line 55 of Figure 4.

The link forming the subject matter of this application is made of platemetal and comprises a body 1 having rounded end edges 2 and parallellongitudinal edges 3 and 4, the body having overhanging arms 5, the ends6 of which'are spaced apart to define an entering throat '7, there beingopenings 8 located partly in the body 1 and partly in the arms 5 andforming inwardly projecting lugs 9 at the ends 6 of the arms 5,

the openings 8 forming notches 10 in the inner edges of the arms 5.There is an inwardly projecting rib 11 along the inner edge of the body1, the inner edge 12 of the rib 11 being parallel to the edge 3. When apair of pliers or a like tool is applied to the arms 5 and to the body1, as shown in dotted line in Figure 1, the arms 5 may be bent at thenotches 10, because they are weakened there, to decrease the spacebetween the lug 9 and the rib 11, thereby closing the link partially onthe chain wherewith the link is assembled. The rib 11 is of such lengthand shape as to reinforce the body 1 when the arms 5 are bent at thenotches 10 as aforesaid.

Two links, constructed as above described, may be placed side byside,'as in Figure 3, the entering throats 7 facing in oppositedirections, one link closing the throat of the other link, and themembers 14 of a cross chain in, an anti-skidding device, or the likebeing received in the openings of the links, the members 14 beinginsertable by way of the throats 7. When the article comes into contactwith the ground, the links of Figure 3 are moved transversely intoalinement, as shown in Figure 4, and the space between the ribs 11 ofthe links is decreased to such an extent as to preventthe chain members14 from shifting from one end of the device to the other.

I claim:

A link of the class described comprising a body having overhanging armsof like out line, there being an inwardly projecting rib along the inneredge of the body, the rib having a straight and continuous longitudinaledge, the ends of the arms overhanging said longitudinal edge of the riband being spaced apart to define an entering throat extended unbrokenlybetween the arms, there being openings located partly in the body andpartly in the arms, the openings forming lugs at the ends of the arms,the lugs projecting inwardly toward said longitudinal edge of the rib,the openings forming notches in the inner edges of the arms, the armsbeing wider at the lugs than at the notches, the link being widestacross the rib, and the arms tapering to the lugs, thereby to render thearms bendable at the my own, I have hereunto aflixed my signanotches todecrease the space between the hire in the presence of two Witnesses.lugs and said loiwitudinal ed e of the rib, and the rib being of suchlength and shape HORACE CLARK 5 as to reinforce the body against bendingVitnesses:

when the arms are bent as aforesaid. DORA M. H0011, In testimony that Iclaim the foregoing as RALPH L. K NG.
